Manufacturer

Pyi Inc

<h3>About PYI Inc.</h3><p>Founded in 1981 and headquartered in Lynnwood, Washington, PYI Inc. has spent more than four decades earning its reputation as a leading manufacturer and distributor of high-quality marine, boat, yacht, and ship equipment. With a catalog that spans everything from precision propellers to sealing systems and rigging hardware, PYI has become a trusted name among boat builders, boatyards, and passionate mariners worldwide.</p><p>What sets PYI apart is a steadfast commitment to engineering products that solve real problems on the water. Rather than offering a broad commodity catalog, the company focuses on purpose-built marine solutions — components engineered for the specific demands of saltwater environments, prolonged exposure to the elements, and the reliability standards required when you're miles from the nearest marina.</p><h3>Flagship Products &amp; Innovation</h3><p>PYI is perhaps best known for its <strong>PSS Shaft Seal</strong> line — a packless, dripless mechanical face seal for propeller shafts that has become the number-one selling marine mechanical seal worldwide. The PSS eliminates the constant adjustment and bilge water intrusion associated with traditional packing glands, and it is installed as standard equipment by many of the world's most reputable boat builders. For boaters looking for proven <a href="/7513-pyi-inc-gaskets-seals-201268">marine gaskets and seals</a>, the PSS system represents a gold standard of reliability and low maintenance.</p><p>PYI is also the exclusive North American distributor of <strong>Max-Prop</strong>, the industry-leading feathering propeller brand renowned for its performance under sail and engine power alike. Beyond propulsion and sealing, the company distributes an expanding suite of marine products including KiwiGrip non-skid coatings, Jefa rudder systems, Fendertex fenders, and R&amp;D Marine engine mounts — making PYI a genuine one-stop resource for serious sailors and powerboaters.</p><h3>Marine Hose Clamps Built for the Job</h3><p>Complementing its sealing products, PYI manufactures its own line of <a href="/7513-pyi-inc-hose-clamps-202096">marine hose clamps</a> designed specifically for below-waterline and demanding marine environments. These clamps are built to pair seamlessly with the PSS Shaft Seal system — in fact, hose clamps are a critical component of proper PSS installation and maintenance. PYI also offers its innovative <strong>Clamp Jacket</strong>, a durable EPDM rubber sleeve that slips over exposed hose clamp tails to protect workers from cuts and give installations a clean, professional finish. The Clamp Jacket is used by professionals ranging from independent boat mechanics to the U.S. Coast Guard.</p><h3>A Culture of Customer Service</h3><p>Over more than 40 years in business, PYI has served hundreds of thousands of customers across the globe — and the company's reputation for responsive, knowledgeable customer service is nearly as well regarded as its products. PYI also operates a full-service machine shop specializing in CNC-machined marine, aerospace, and industrial components, further demonstrating the engineering depth behind every product that carries the PYI name.</p><p>Whether you're outfitting a new build, upgrading an aging vessel, or sourcing critical replacement parts, PYI Inc. delivers the marine-grade quality and technical expertise that serious boaters depend on.</p>
